Particulate Matter (PM) Sensor - SPS30

The Sensirion Particulate Matter Sensor SPS30 is a compact, high quality, optical particle sensor that uses laser scattering and Sensirion’s innovative contamination resistance technology to achieve superior binning and particle measurement. This sensor allows users to measure mass concentration and number of particles of PM1.0 µg/m3, PM2.5 µg/m3, PM4 µg/m3, and PM10 µg/m3.

The compact form factor, measuring just under 41mm x 41mm x 12mm, combined with a sensor lifetime over 8 years and a self cleaning procedure, makes the SPS30 the perfect sensor for projects in difficult to access locations.

Sparkfun has designed and included an easy to use 5-pin cable to make using the SPS30 a snap. The 1.5mm connector is broken out to 5 breadboard friendly wires color coded to make hooking up the SPS30 easy. The SPS30 has a five pin interface that can communicate over two different protocols: UART and I2C. The SPS30 requires a 5V power supply, but can work with 3.3V and 5V microcontrollers.
